Find the volume of one brick by multiplying the length by the height by the width to find the volume for one brick.

Then multiply the volume for one brick by the number of bricks they want to make to find the total amount of concrete needed.

Volume of brick: 5 x 4 x 2 = 40 cm^3

Total concrete needed: 1600 x 40 = 64,000 cm^3

Find the slope. (4, 10) and (-2,-5)​
marta [7]

Answer:

Slope in fraction form = 5/2

Slope in decimal form = 2.5

========================================================

Work Shown:

m = (y2-y1)/(x2-x1)

m = (-5-10)/(-2-4)

m = (-15)/(-6)

m = (-3*5)/(-3*2)

m = 5/2 slope in fraction form

m = 2.5 slope in decimal form

-----------------

Explanation:

The first step is the slope formula where (x1,y1) and (x2,y2) are the two points the line goes through.

I used (x1,y1) = (4,10) and (x2,y2) = (-2,-5)

The slope formula basically says "subtract the y values, then subtract the x values in the same order. Then divide the two differences".

Or you can think of it as

slope = rise/run

rise = y2-y1 = change in y

run = x2-x1 = change in x
